Design of Solder Quality Inspection System Based on Machine Vision

摘要

The electronic water pump for vehicles adjusts the working state of the water pump with the help of the electronic control unit, and then pressurizes the coolant, to circulate the coolant in the cooling system to ensure that the engine temperature does not exceed the limit threshold and can work normally. Therefore, it is a very important link to inspect internal circuit boards in the production of water pumps. Traditional manual inspection has limited working time, while automatic machine vision inspection can perform 24-hour uninterrupted inspection. Compared with manual inspection, it is more reliable and stable, which has advantages in speed, and has a wide range of industrial applications. According to this, this paper designs a solder joint inspection system based on machine vision, which can detect the status of solder joints and feed back the current soldering results to the workers. The method solves the problem of automatically detecting the welding quality of the circuit board in the manual welding process, greatly improves the production efficiency of the workshop production line, and shortens the product production cycle.
